Article on Forbes.com featuring an interview with NYSE Euronext Executive Vice President, Scott Cutler (May 10, 2011).

NYSE: You Are Witnessing A “Complete Crushing” of the NASDAQ

May. 10 2011—8:00 pm

Forbes caught up with Scott Cutler of the New York Stock Exchange.

As the New York Stock Exchange fends off an unsolicited takeover bid by the Nasdaq, competition for prominent stock listings— especially those of the high-profile tech variety— has become cutthroat. Technology has traditionally been Nasdaq turf. The Nasdaq exchange still plays host to some world’s top technology companies including Intel, Google and Microsoft.

Just not for long, says the Big Board.

Last week, LinkedIn announced it will list its shares on the NYSE under the symbol “LNKD” becoming the latest high-profile tech company to shun the Nasdaq in favor of the NYSE. Pandora announced it will also be joining the NYSE under the coveted stock symbol “P”. Hot storage outfit Fusion-io said it will also list with the Big Board.

Renren, the “Facebook of China,” began trading on the NYSE last week.

Meanwhile, SuccessFactors recently announced the transfer of its listing from the Nasdaq to the NYSE. The NYSE is expected to announce it has poached another Nasdaq listee later this week.

Those bragging rights are critical as NYSE CEO Duncan Niederauer tries to convince NYSE Euronext shareholders to reject Nasdaq’s hostile big in favor of a friendly merger with Frankfurt-based Deutsche Börse, a move that would create the world’s largest exchange owner. Niederauer has his work cut out for him: Nasdaq’s offer represents a $1.3 billion premium over the Deutsche Börse deal. The NYSE has already twice rejected a meeting with Nasdaq chief executives, saying the hostile bid would lead to too much debt and regulatory concerns. At a UBS financial services conference today, Nasdaq CEO Robert Greifeld said he plans to move ahead with a tender offer “within weeks.”

I caught up with Scott Cutler, executive vice president at the NYSE, to discuss what he calls the Nasdaq’s “propaganda campaign,” recent wins for the Big Board and why he thinks the proposed merger with Deutsche Börse would make more sense for NYSE shareholders than going with “the other guy.”

Let’s start with the series of coups lately for the Big Board.

LinkedIn, Pandora and RenRen all decided to go with the NYSE over the Nasdaq. What’s the back story there?

While the NASDAQ has been raging their propaganda campaign, we’re winning the ground war—especially on the IPOs. If you look at everything that’s happened so far this year, from the large private equity transactions—we have won every single one— to the technology transactions— RenRen, LinkedIn, Pandora, The Active Network, Freescale— it’s really been a complete sweep of the table for the NYSE. We remain very focused on extending our global


community to emerging growth, technology focused companies wherever they’re coming from. We’re seeing these companies come from the Valley, obviously from the Midwest, New York, China. We are going to see one of our first technology-focused listings from Latin America later on this year.

Which listing would that be?

I can’t say.

So what’s the pitch? Why should a technology-focused company go with the NYSE?

The pitch for us continues to be a business partnership that leverages our brand, our network and our community for their business benefit. If you looked at LinkedIn, what brought us to the table was our track record of technology, our track record in the Valley and the relationship we’ve built with their management team over the last couple years. What brought us over the finish line was a partnership that leveraged our professional community with theirs. There are great business synergies with a lot of the companies we’re working with and I think that’s why we win.

The Nasdaq recently suggested that the NYSE was losing ground in stock listings.

That statement is absolutely ridiculous. Look at the facts.

We were number one in the world in the first quarter in capital raising. Nasdaq was number ten. We represented 66% of the technology IPOs in the first quarter. Every single private equity firm—100%– listed on the NYSE. It has essentially been a complete crushing of the Nasdaq.

Of companies that are already listed, we’ve had four transfers so far this year, even with the proposed merger with Deutsche Börse. We’ve had Imax and SuccessFactors. Successfactors announced their transfer from Nasdaq, their listing on our Euronext market and their listing on Deutsche Börse— and that deal hasn’t even closed yet. And later on this week, we will be announcing another tech transfer. We haven’t had any that have gone the other way. Eighteen have come from Nasdaq. So there’s actually not one metric or quadrant in the world or sector in which Nasdaq is beating the NYSE. Not one.

Are these companies coming to you? Or is this part of a broader outreach strategy?

It’s both. We have an active outreach that continues to be an area of intense competition. It’s similar to the IPO landscape where we develop relationships and convince people of the value proposition. Imax is making this move because they wanted to show the world that they are a global company with a global presence and their partnership with the NYSE could deliver that. SuccessFactors was about global partnerships and global listing. As companies are evolving, they are looking for global partners and finding that at the NYSE.

Let’s talk about the proposed takeover.

Proposed merger, right?

Okay, the proposed merger with Deutsche Börse.

The NYSE is the leader in global listings. We are the leader in cash equities, but we are the number four player globally in the derivatives marketplace. So the combination with Deutsche Börse really creates the largest exchange group in the world by market capitalization, the leader


in the derivatives market and the leader in technology and market data. That global leadership position is where we want to be.

I understand Duncan Niederauer is now meeting with shareholders every day to garner support for the Deutsche Boerse merger. What’s next?

There’s a shareholder vote in early July and shareholders will be voting on the DB deal. In light of Nasdaq’s hostile deal, we have to convince shareholders that this is the right strategy and they’re getting the best value out of this transaction.

Everyone’s holding their breath for a few select companies to go public. What are you doing to ensure those companies list on the Big Board?

We are very focused on the next emerging category leaders and we are going to focus on every space in which we compete, which is everywhere. There has been a change in the mindset. As more of these companies go public on the NYSE—and succeed— it creates a lot more excitement around the opportunity to go public. So I think the actors that will go public in the next few weeks– LinkedIn, Pandora—are a teaser for some really significant transactions to come, whether that’s Groupon or Gilt or Facebook or others. I don’t know if the NYSE’s position in the marketplace has ever been stronger.

What role is the NYSE playing in opening up access to markets?

We’ve been pushing for an amendment to Sarbanes-Oxley… which provides more companies with greater access to public markets at lower thresholds.

We’ve also been advocating on behalf of capital markets in the U.S.

It’s a role and responsibility we take pretty seriously.

Are you reserving any specific stock symbols we should know about? We do.

If a company wants a symbol, we’ll reserve it for them but your symbol does not necessarily represent which market you’re going to list on anymore.
